Help, broken pivot bolt threaded side still in frame

Was loading up to go for a ride and felt some play in my bikes rear end. I sourced the looseness to the floating pivot above the shock. At first it looked like I just lost the locking nut. But I pulled out the bolt to reveal an even worse scenario. The bolt snapped at the base of the threads. The threaded side is still in the pivot and holding the shock so I can't even swing it out. So how do I back out the broken threaded side piece of hardware?

First off @MrGreedom good job for recognizing something wasn't right and then taking the time to figure out the problem. Having managed machine shops pretty much my whole life I have run in to this more than a few(hundred) times. I have a technique that for me has been hugely successful. Nothing against using an EZout but my success rate with them is low. What I like to do is use a small center drill(#1) to slowly and carefully get a decent center hole started. Then follow that with a good drill(probably 1/8" in your case) that only needs to be drilled 1/8" deep or so. Then take a slightly larger torx bit(t20 or t25) and solidly tap the torx bit in to the hole you drilled. The star shape of the torx bit gets a good bite and creates it's own spline and can then be used to just thread the busted bolt out. Same basic idea as the ez-out but way higher success rate for me.

If you're lucky and the bolt isn't too tight ( soak it with penetrant) it will just wind itself out when you drill it. The drill will twist the same way as the threads and just push it thru.
Probably not on the pilot hole, but maybe on the next step up.

Fixed it! No drilling required. What I did: remove the right pivot where the broken thread was lodged. Once off, I could grip the bolt and easily unscrew the remaining part. Clean off built up dirt I can't usually get to, replace everything, and torque it back to spec. Luckily my good buddy George still has the demo BH we removed the bolt from it for my bike so I can be rolling asap. Replacement bolt for the demo is in the mail. Nice having a riding buddy that owns a LBS that trusts me to use a stand and tools.

Awesome!

So now back to the original question - why did your hardware fail on a brand new bike? Did you ask BH?

I did send an email to the BH warranty/service dept. I told them I wanted the mechanical failure documented since I've only ridden a few hundred miles on this bike. They responded that they have gotten this problem before. I guess I'm in the same category as @mtnbikej stronger than steel.
